A combined total of $33,000 is invested in two bonds that pay 5% and 6.5% simple interest. The annual interest is $2,010.00. How much is invested in each bond?
Answers
Answer: $9,000 is invested in the 5% bond, and $24,000 is invested in the 6.5% bond.
Step-by-step explanation: x + y = 33,000 (the full sum contributed)
We too know that the yearly intrigued earned is $2,010.00, which is the whole of the intrigued earned from each bond. Utilizing the equation for basic intrigued:
intrigued = principal x rate x time
ready to calculate the intrigued earned from each bond:
0.05x (for the 5% bond)
0.065y (for the 6.5% bond)
So we have another condition:
0.05x + 0.065y = 2,010
Presently we have two conditions with two factors, which we are able illuminate utilizing substitution or end.
Let's utilize substitution:
x + y = 33,000 --> y = 33,000 - x
0.05x + 0.065y = 2,010 --> 0.05x + 0.065(33,000 - x) = 2,010
Streamlining:
0.05x + 2,145 - 0.065x = 2,010
-0.015x = -135
x = 9,000
So the sum contributed within the 5% bond is $9,000, and the sum contributed within the 6.5% bond is:
y = 33,000 - x = 33,000 - 9,000 = $24,000
Eating at the all-you-can-eat buffet at your favorite restaurant currently costs
$18.50, and increases in cost by 6% each year. What will this buffet cost in 6 years?
$26.24
$30.23
$27.13
$31.64
Answers
A = P(1 + r)^n
where A is the final amount, P is the initial amount, r is the annual interest rate as a decimal, and n is the number of years.
In this case, P = 18.50, r = 0.06, and n = 6. Plugging these values into the formula, we get:
A = 18.50(1 + 0.06)^6
A = 18.50(1.06)^6
A = 18.50(1.4185)
A = 26.23
Therefore, the cost of the all-you-can-eat buffet in 6 years will be approximately $26.23, which is closest to option A.

Melissa drew a right triangle.
The perimeter of the triangle is 9+√41.
The hypotenuse is of length ✓41.
Using this information, what is the length of the other
two sides of the triangle?
Answers
Answer:
Let's denote the two legs of the right triangle as a and b, and the hypotenuse as c. We know that c = √41, so we can use the Pythagorean theorem to relate a and b to c:
c^2 = a^2 + b^2
Substituting c = √41, we get:
(√41)^2 = a^2 + b^2
41 = a^2 + b^2
We also know that the perimeter of the triangle is:
perimeter = a + b + c = 9 + √41
Substituting c = √41, we get:
a + b + √41 = 9 + √41
a + b = 9
Now we have two equations with two unknowns (a and b):
a^2 + b^2 = 41
a + b = 9
We can solve this system of equations by substitution. Solving the second equation for a, we get:
a = 9 - b
Substituting this into the first equation, we get:
(9 - b)^2 + b^2 = 41
81 - 18b + 2b^2 = 41
2b^2 - 18b + 40 = 0
b^2 - 9b + 20 = 0
(b - 4)(b - 5) = 0
So we have two possible solutions: b = 4 and b = 5. We can find the corresponding value of a using a = 9 - b:
a = 5 and b = 4 or a = 4 and b = 5
Therefore, the two legs of the right triangle are 4 and 5.
solve the inequality and graph the solution on the line provided.
5x - 15 < 10
Answers
Add 15 to both sides of the inequality to isolate the term with x:
5x - 15 + 15 < 10 + 15
5x < 25
Divide both sides of the inequality by 5 to solve for x:
5x/5 < 25/5
x < 5
Therefore, the solution for the inequality is x < 5.
To graph the solution on the number line, we can draw a line with an open circle at 5 (since the inequality is less than, not less than or equal to), and shade the part of the line to the left of the circle to represent all the values of x that satisfy the inequality. Here's a rough sketch:

The shaded region is on the left side of the open circle.
Answer: x < 5, see attached for the graph.
Step-by-step explanation:
To solve, we will isolate the variable.
Given:
5x - 15 < 10
Add 15 to both sides of the equation:
5x < 25
Divide both sides of the equation by 5:
x < 5
For the graph, we will use an open circle because this is only less than (<), not less than and equal to.
Then, since x is all values less than 5, we will shade our arrow to the left of 5. See attached.

During certain time periods at a hospital, patients arriving at the emergency room have waiting times that are uniformly distributed between 0 and 7 minutes. Assume that a patient is randomly selected, and find the probability that the waiting time is less than 0.75 minutes. (Round to three decimal places)
Answers
Since the waiting times are uniformly distributed between 0 and 7 minutes, the probability density function (PDF) of the waiting time is:
f(x) = 1/7 for 0 ≤ x ≤ 7
0 otherwise
To find the probability that the waiting time is less than 0.75 minutes, we need to integrate the PDF from 0 to 0.75:
P(X < 0.75) = ∫[0,0.75] f(x) dx
P(X < 0.75) = ∫[0,0.75] 1/7 dx
P(X < 0.75) = [1/7 * x] [0,0.75]
P(X < 0.75) = 1/7 * 0.75
P(X < 0.75) = 0.1071
Therefore, the probability that the waiting time is less than 0.75 minutes is 0.1071 (rounded to three decimal places).

Find the missing side of the triangle 12, 34° and 90°
Answers
Answer:
To find the missing side of a right triangle given an angle and a side, you can use trigonometric functions. In this case, we have the angle opposite the missing side, so we can use the sine function.
The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse. Therefore, we can set up the following equation:
sin(34°) = opposite / 12
To solve for the opposite side, we can multiply both sides by 12:
opposite = 12 * sin(34°) ≈ 6.60
Therefore, the missing side of the triangle is approximately 6.60 units long.

2. A gift is packed in a rectangular box (rectangular prism) of dimensions 15 in, 10 in, and 8 in and it needs to be wrapped with gift paper. How much gift paper is required to wrap the gift box?
length= 5 in , width= 4 in, height= 3 in
Answers
length, l=16in
width, b=13in
thickness, t=3in
To Find:-
Area of wrapping paper required.
Explanation:-
Since, wrapping paper is to be wrapped over the whole rectangular box.Therefore, we have to calculate the total surface area of the rectangular box.

Therefore, 590 of paper is required to wrap the whole rectangular box.
=700 sq in
= 94 sq in
Step-by-step explanation:
To find the amount of gift paper required to wrap the gift box, we need to find the total surface area of the rectangular prism. The total surface area is the sum of the areas of all six faces of the rectangular prism.
The formula for the surface area of a rectangular prism is:
Surface area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
For the given rectangular prism with dimensions 15 in, 10 in, and 8 in, we have:
l = 15 in, w = 10 in, h = 8 in
Substituting these values into the formula, we get:
Surface area = 2(15)(10) + 2(15)(8) + 2(10)(8)
Surface area = 300 + 240 + 160
Surface area = 700
Therefore, the amount of gift paper required to wrap the gift box is 700 square inches.
For the second part of the question, we need to find the surface area of the rectangular prism with dimensions 5 in, 4 in, and 3 in. Using the same formula, we have:
l = 5 in, w = 4 in, h = 3 in
Surface area = 2(5)(4) + 2(5)(3) + 2(4)(3)
Surface area = 40 + 30 + 24
Surface area = 94
Therefore, the amount of gift paper required to wrap the second gift box is 94 square inches.

Determine the slope of the line and explain its meaning in terms of the real-world scenario.
The slope of the line is 6, which means that the swimmer will finish the race after 6 minutes.
The slope of the line is 24, which means that the swimmer must complete 24 laps in the race.
The slope of the line is −4, which means that the swimmer will complete 4 laps every minute.
The slope of the line is negative one fourth, which means that the swimmer completes a lap in one fourth of a minute.
Answers
since i don't see the graph ill go with... B The slope of the line is 24, which means that the swimmer must complete 24 laps in the race.
-24/6 = -4
Step-by-step explanation:
The slope of the line can be found using the formula:
slope = (change in y) / (change in x)
In this case, we can use the two given points on the line: (0, 24) and (6, 0).
Change in y = 0 - 24 = -24
Change in x = 6 - 0 = 6
Therefore, slope = -24/6 = -4
This means that for every minute that passes, the swimmer completes four laps. The swimmer's pace is steady and consistent throughout the race, gradually decreasing the number of laps remaining until they finish at 0 after six minutes.
Answer:
The slope of the line represents the rate of change in the number of laps remaining per unit of time (in this case, per minute). In other words, it tells us how quickly the swimmer is completing laps.
Since the slope of the line is -4, this means that the swimmer is completing 4 laps every minute. This could be interpreted as the swimmer's pace or speed in the race. The negative sign indicates that the number of laps remaining is decreasing over time, which is expected as the swimmer completes more and more laps.
It's worth noting that the slope is constant throughout the race, meaning that the swimmer is maintaining a consistent pace. This information could be useful for the swimmer and their coach in terms of planning and pacing the race.
